I emailed and then called support (twice) and pointed it out. Even after escalating the issue as far as I could, it resulted in no action. Even a cursory review should have stopped the title from being published, since it was of ridiculously poor-quality (analogous to someone publishing a title called "Harry Potter and the Sorcerer's Legacy by J.K. Rowling" and having an apparently legit front cover but an interior filled with almost nonsensical, semi-autogenerated text). The fact that a title like this can be published on the platform at all indicates that the review process for new titles is sadly lacking any application of common sense.
I'm appreciative that Amazon is pushing the envelope in supporting self-publishers via their print on demand services, but by failing (and actually refusing) to police it they are giving a bad name to the whole enterprise. Through their inaction they are encouraging the copyright infringers and scammers to turn what could/should be a great service into a toxic ecosystem.
